<div class="warning">
<p><code class="literal">g_volume_monitor_adopt_orphan_mount</code> has been deprecated since version 2.20 and should not be used in newly-written code.</p>
<p>Instead of using this function, <a class="link" href="GVolumeMonitor.html" title="GVolumeMonitor"><span class="type">GVolumeMonitor</span></a>
implementations should instead create shadow mounts with the URI of
the mount they intend to adopt. See the proxy volume monitor in
gvfs for an example of this. Also see <a class="link" href="GMount.html#g-mount-is-shadowed" title="g_mount_is_shadowed ()"><code class="function">g_mount_is_shadowed()</code></a>,
<a class="link" href="GMount.html#g-mount-shadow" title="g_mount_shadow ()"><code class="function">g_mount_shadow()</code></a> and <a class="link" href="GMount.html#g-mount-unshadow" title="g_mount_unshadow ()"><code class="function">g_mount_unshadow()</code></a> functions.</p>
</div>
<p>This function should be called by any <a class="link" href="GVolumeMonitor.html" title="GVolumeMonitor"><span class="type">GVolumeMonitor</span></a>
implementation when a new <a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a> object is created that is not
associated with a <a class="link" href="GVolume.html" title="GVolume"><span class="type">GVolume</span></a> object. It must be called just before
emitting the <em class="parameter"><code>mount_added</code></em>
 signal.</p>
<p>If the return value is not <a href="https://developer.gnome.org/glib/unstable/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, the caller must associate the
returned <a class="link" href="GVolume.html" title="GVolume"><span class="type">GVolume</span></a> object with the <a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a>. This involves returning
it in its <a class="link" href="GMount.html#g-mount-get-volume" title="g_mount_get_volume ()"><code class="function">g_mount_get_volume()</code></a> implementation. The caller must
also listen for the "removed" signal on the returned object
and give up its reference when handling that signal</p>
<p>Similary, if implementing <a class="link" href="GVolumeMonitor.html#g-volume-monitor-adopt-orphan-mount" title="g_volume_monitor_adopt_orphan_mount ()"><code class="function">g_volume_monitor_adopt_orphan_mount()</code></a>,
the implementor must take a reference to <em class="parameter"><code>mount</code></em>
 and return it in
its <a class="link" href="GVolume.html#g-volume-get-mount" title="g_volume_get_mount ()"><code class="function">g_volume_get_mount()</code></a> implemented. Also, the implementor must
listen for the "unmounted" signal on <em class="parameter"><code>mount</code></em>
 and give up its
reference upon handling that signal.</p>
<p>There are two main use cases for this function.</p>
<p>One is when implementing a user space file system driver that reads
blocks of a block device that is already represented by the native
volume monitor (for example a CD Audio file system driver). Such
a driver will generate its own <a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a> object that needs to be
associated with the <a class="link" href="GVolume.html" title="GVolume"><span class="type">GVolume</span></a> object that represents the volume.</p>
<p>The other is for implementing a <a class="link" href="GVolumeMonitor.html" title="GVolumeMonitor"><span class="type">GVolumeMonitor</span></a> whose sole purpose
is to return <a class="link" href="GVolume.html" title="GVolume"><span class="type">GVolume</span></a> objects representing entries in the users
"favorite servers" list or similar.</p>
